It's flowing towards the engine from the fuel tank.I was only guessing, as it appears to be crushed as a result of excessive pressure or suction depending where it's located in the system.
You don't have a gauge in the car or on the regulator or schrader valve?Don't know what it's set at, just left the dyno 400 miles ago..didn't have any issues until recently..missing at 5k 18 psi at wot..barely getting any fuel pressure now..
Yeah, im def not seeing that. Something happened shortly after I picked it up from the shop. We all think it is pump related.If you're running a boost reference FPR, then pressure should be set around 39-40psi with the vacuum line disconnected. When it's reconnected, your gauge should read 39-40 psi minus half of whatever your car makes for vacuum at idle. So, for example, my car is set at 40psi with the vac line disconnected and makes 14inhg of vac at idle. So, 40-7=33. When I connect my vac line to the FPR, my gauge reads 33 at idle. Then adds 1psi of pressure for each pound of boost made.
If you're not running a boost reference regulator, then the gauge should read whatever you set the FPR to.
